Mine was purchased as a Garmin unit from a Garmin dealer and has a one year warranty. I'm just fed up sending it back and forth...will get to it eventually. Dealer has been brilliant sending me a new one before I return the faulty one, but even he is getting pissed off with this routine.
IMHO it's a design fault with this particular body shape of unit. How can it be waterproof when you can see the guts of the thing when the card is removed. Friend has a 2820 with same fault, also on his 3rd unit
Garmin also admitted on the phone that the BMW mount and Ram mounts were a 'bad' design not allowing the vent holes to be open when mounted on a motorcycle. Their words 'Not ideal' & 'Bad design' again, vent holes and waterproof don't compute in the same sentence ?
Not sure what warranty BMW will give you on the unit, but if it came with the bike and the bike has more than that, then go for it. Not sure if Insurance based warranty would cover it though.
My unit has a mind of it's own. It keeps changing from 'track up' to 'track north' , far zoom instead of local, even had to turn of the infra-red because when the sun hits it, everything goes haywire and constantly beeps in helmet.
I AM A GARMIN FAN and have been for years, but this particular unit, to me, is a piece of junk soon to be traded in for sometihnge else.
